Re: Reverse loading and using a shinny Aluminum pressure plate

[Rolland Rainbow Elliott <X93ELLIOTT1@xxxxxxxxx>]

About a week ago I asked if anyone in this group had reverse loaded HIE into
their cameras and also if anyone had experimented with covering their
camera's back pressure plate with shinny aluminum foil to see if it increased
the halo effect that HIE has due to its lack of an anti-haliation layer.

Well the other day I went outside with my Nikon and my B+W 092 filter
(Wratten equivalent is the 89B) and took some pictures with the film reverse
loaded (so that the emulsion side of the film touched the pressure plate of
my camera).  I also had covered the pressure plate with aluminum foil.  
I set my EI to 3200 and metered TTL (through the lens) using my camera's
matrix metering system.  (by the way I disagree with everyone who says you
can't compose or meter through an 89B filter, It's kind of dark, but
deffinitely lets in enough light, especially during a sunny day)

Later, I developed the film in TMax 1:4 at 72degrees F for 5 minutes.  The
results weren't that exciting.  The negatives looked like any other HIE
negatives I've seen.  Reverse loading the film doesn't seem to have any
effect; which is what I suspected, since the film doesn't have an
anti-halation backing.  

As far as the effect of the aluminum foil.....   I can't draw any conclusions
yet, because I have not made any prints from the negatives, I have just
looked at a contact sheet.  The aluminum foil might have increased the
halation effect, but it will be hard for me to say, until I can see a bigger
print.  At any rate, the aluminum foil didn't fog the negatives, like I
thought it might, and it didn't change my ISO setting like I though it would. 
My standard EI when using an 89B TTL is 3200, and this also worked with the
aluminum backing.  

So, give aluminum foil a try and tell me if you think it makes a difference. 
I'll let you know what I see as soon as I make bigger prints.
